The area in square feet that will be added to the garden is 44 square feet.
Length of square garden = 8 feet
Area of Square garden = [tex](side)^{2}[/tex] = [tex](8)^{2}[/tex] = 64 square feet
On enlarging the square to a rectangle, length rectangular garden is (8+4)feet i.e.,12feet and width of rectangular garden is (8+1)feet i.e.,9feet.
Area of rectangular garden = (length × width)
= (12 × 9) square feet
= 108 square feet
The area in square feet that will be added to the garden = (Area of rectangular garden - Area of Square garden)
= (108 square feet - 64 square feet)
= 44 square feet
